CLOCK.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed December 6,1905. Serial No. 290,653.

To all whom it may concern:

Be it known that I, CLARKE OONWELL, of Larchmont, in the county ofWestchester, State of New York, have invented certain new and usefulImprovements in Clocks, of which the following is a specification.

This invention pertains to certain new and useful improvements inclocks, and relates more particularly to that class of clocks which areadapted for striking ships time.

The invention has for its object the production of a clock of thischaracter which will strike the hours and half hours in close imitationto the usual bell strokes by which time is indicated on shipboard.

A further object is to provide means which will cause the initial strokeof the striking hammer to always occur upon the first portion of adouble stroke.

A further object is to provide means whereby a double stroke is securedwith a single hammer.

A further object is to provide an improved pin disk for operating thestriking hammer, together with means for automatically placing said pindisk into and out of operative relation with said hammer.

A further object is to provide pin mechanism which will automaticallyreturn to a normal position after each operation of the strikingmechanism.

In carrying out my invention I provide a gear meshing with the strikingtrain, said gear being keyed to a suitable shaft and provided withspaced apart openings to receive the pins of a pin disk loosely mountedon the same shaft, said gear and pin disk being normally held separatedby any suitable means, such as a spring. Suitable means, operated by thehour hand shaft, is provided to move the pin disk toward the perforatedpinion against the action of the separating means, whereby the pins ofsaid disk protrude through the openings in the gear, this movement beingtimed to occur simultaneously with the operating of the striking trainwhich rotates said gear. Upon completion of the striking operation thedisk and gear are automatically separated, and said disk reverselyrotated to its normal position by any suitable means, such as a springor the like.

The invention will be hereinafter more fully described and particularlypointed out in the claims.

In the accompanying drawingr-Figure 1 is a front view of a clock withthe face removed, illustrating my invention. Fig. 2 is an edge viewthereof. Fig. 3 is an enlarged edge view of the pin disk and itsadjuncts. Figs. 4, 5 and 6 are details.

Referring to the drawing, 10 designates a gear keyed to a shaft 11 andmeshing with a pinion 12 of the striking train which latter may be ofany'preferred construction. The shaft 11 is also provided with a secondgear meshing with the main driving gear 13 of the striking train.Mounted on shaft 11 adjacent gear 10 is a pin disk 14 which is free torotate on said shaft and provided with a plurality of pins 1.5 arrangedin pairs and adapted to protrude through openings 16 arranged in thegear 10. Said gear and pin disk are normally separated by any suitablemeans, preferably a spring 17 as shown. Mounted loosely upon shaft 11 isa cam gear 18 provided with a cam 19 which is adapted to engage asimilar cam 20 also loosely mounted on said shaft 11 and interposedbetween the cam gear and the disk 14. The cam 20 is free to reciprocateupon the shaft 11 but is prevented from rotating thereon by means of anarm 21 engaging the shaft 22 of the pinion 12. The gear 18 "is rotatedby a similar gear 23 seemed to the sleeve which carries the minute hand,said sleeve being rotated in the usual manner by the time train. By thisarrangement the cam 19 is completely rotated once in each hour. In thisconnection it will be noted that I do not claim any specific time trainand therefore have not illustrated the same in detail. The cams l9 and20 are each provided with double cam faces 24, whereby the pin disk 14is moved into engagement with the gear 10 once every half hour. The pindisk 14 is provided with a stop 25 which is held normally in engagementwith the winding shaft 26 of the striking train by means of a coilspring 27.

The operation is as follows:The gears 18 and 23 be ing of the same sizethe cam 19 acts upon cam 20 to move the pin disk 14 into engagement withthe gear 10 once every half hour. Simultaneously with the lateralmovement of the disk 14 the striking train is released by the releasingmechanism R which may be of any preferred form common to strikingclocks, whereupon gear 10 is free to revolve under the action of thedriving gear 13. In this manner the pins will trip the lever L of thestriking hammer. The pins being arranged in pairs will cause said hammerto operate with a double stroke to correspond to the stroke of nauticalbells which are struck in pairs. After the stroke has been made, theonward movement of the minute hand sleeve and gear 23 carries the gear18 and its cam forward so that the cams l9 and are in such position asto permit lateral movement of the cam 20 and disk 14, under theinfluence of spring 17, whereby the pins 15 are disengaged from gear 10.Just as soon as said disk 14 is disengaged from the gear 10, the disk isreverscly rotated under the influence of spring 27 until the stop engages shaft 26, said stop being so located as to always stop the disk 14with its pins opposite the openings 16 in gear 10, the striking trainbeing so constructed that the gear 10 always stops with its openings inthe same relative position.

The advantages and operation of my improved clock are apparent from whathas been said. It will be observed that by arranging the hammcroperating pins in will insure that the initial stroke o the hammer willalways occur upon the first portion of the double stroke. It will alsobe noted that by this arrangement I am enabled to secure the doublestroke with a single hammer. It will be further observed that I haveprovided simple and eflicient means for automatically placing the pindisk into and out of operative relation with the striking hammer, andhave insured the returning of the pin disk to its normal position. ItWill be particularly observed that the parts are so arranged as not tobe affected by pitching or rolling of the vessel in rough Weather.
